On February 27, the Mobile World Congress (MWC) was held in Barcelona. As an annual industry congress, MWC has become the most influential exhibition in the mobile communication industry worldwide.

NB-IoT, as popular as 5G, also gained great visibility in MWC. Meanwhile, as in the major cities of Spain, the leading UK international communication enterprise - Vodafone, has built a commercial NB-IoT network covering the whole cities. Which has brought NB-IoT a brilliant opening in MWC.

Goldcard’s NB-IoT smart gas meter made its debut and caught visitors’ eyes in MWC with its high-tech appearance and abundant functions, such as adjustable blocking gas pricing, remote recharging, remote valve control, and alarming. Through integration on Huawei’s OceanConnect IoT platform, Goldcard builds a comprehensive E2E smart gas solution from meters to communication networks, SCADA, data collection, and customer service.

In August 2016, Goldcard worked with Huawei in the filed of NB-IoT technologies, which greatly promoted the application of NB-IoT technologies in smart gas.
